A set of two standard 24-inch bicycle inner tubes, made from butyl rubber and equipped with 32mm Schrader valves, includes two complimentary tire levers for easy installation.

About This Product
**Premium Material:** Crafted from high-quality butyl rubber. It offers superior airtightness, temperature resistance, anti-a-ging properties, and shock absorption capabilities, making it highly durable and resistant to damage.
**Shock-Absorbing & Durable:** Features ultra-thick butyl rubber construction, providing excellent shock absorption and impact resistance to ensure a comfortable and safe ride. The material is robust and temperature-resistant, standing up to daily wear and tear for long-lasting performance.
**Easy Installation:** Simply use a tire lever to easily pry open and remove the outer tire, then replace it with the new inner tube. The installation process is quick and convenient.
**Package Contents:** Includes a pack of two 24 x 2.125 / 2.40 - FV - 48 mm bicycle inner tubes. Suitable for a wide range of scenarios, including mountain biking, road cycling, MTB riding, urban commuting, and off-road adventures.

**Helpful Tips:**
1. **Verify Tire Size:** Before purchasing, please be sure to confirm your bicycle's outer tire size to ensure the tire width falls between 2.125 and 2.40.
2. **Check for Sharp Objects:** Before inserting the new inner tube, carefully inspect the interior of the outer tire and the tire casing for any embedded sharp objects that could puncture the tube.
3. **Pre-inflate Slightly:** Before installing the new inner tube, inflate it with a small amount of air (just enough to give it shape). This prevents the tube from twisting or bunching up during installation, thereby avoiding "pinching" (where the tube gets caught and punctured between the outer tire and the rim) or preventing the outer tire from seating correctly against the rim.
4. **Position the Valve:** Insert the valve stem through the valve hole in the rim. The valve should protrude vertically at a 90-degree angle. Tighten the valve cap to ensure it is securely fastened.
5. **Final Check:** Once installation is complete, verify that the inner tube is fully seated inside the outer tire and is not pinched between the outer tire and the rim (or metal wheel frame). Once confirmed, you may inflate the outer tire to the recommended air pressure level.
6. **Monitor Tire Pressure:** Regularly check your tire pressure; strive to keep your tires properly inflated at all times. Never over-inflate, and conversely, avoid under-inflating. 7. During installation, please avoid using screwdrivers or any sharp tools to prevent accidentally puncturing the inner tube or outer tire.
